This package adds some additional assertions to Test::Unit::Assertions, including: * Assertions for all of the comparison operators (<code>assert_greater_than</code>, <code>assert_less_than_or_equal_to</code>, etc.). Shorter aliases also are provided for these (<code>assert_gt</code>, <code>assert_le</code>, etc.). * An assertion that verifies that a given block raises a specified exception with a specified message (<code>assert_raise_message</code>). This allows full testing of error messages. * An assertion that verifies that a given block contains an assertion that fails (<code>assert_fail</code>), which can be used to test new assertions.
